When temperature increases, the speed of gas molecules ____________; The heavier the molecule, the __________ its speed. Since molecules move at different speeds, we refer to their speeds as ____________ speeds.
Pressure = _________ divided by _________. It is measured in the English system with the units ______ per ________. Pressure is actually caused by ____________ of gas particles. When temperature increases, the number of ____________ increase; also the ___________ of the collisions increase; therefore the pressure ___________. Sketch below the graph of pressure vs temperature for a gas. This is a _______ relationship.
When the number of atoms increases, the number of collisions _____________, this causes an __________ in pressure. This is a ________ relationship; sketch a graph of this relationship below.
When volume increases, the number of collisions ____________, therefore the pressure __________. This is a _____________ relationship. Sketch a graph of this relationship below.
